UCC5672MWP

Overview

The UCC5672MWP is a high-speed digital isolator manufactured by Texas Instruments, designed for SCSI interface applications. It features a single driver configuration housed in a TSSOP-28 surface-mount package. The device operates within a supply voltage range of 2.7 V to 5.25 V and draws a typical operating current of 23 mA. It supports data rates up to 100 Mbps with propagation delays as low as 15 ns. The component functions across an industrial temperature range from 0°C to +70°C and includes integrated termination resistors.

Feature Summary

• Provides galvanic isolation between signal sources and loads for noise immunity
• Integrates on-chip termination resistors to simplify circuit design
• Supports high-speed data transmission suitable for SCSI interfaces

Applications

• SCSI bus interface circuits
• High-speed digital isolation in industrial systems
• Signal isolation for microcontroller peripherals

Procurement Notes

Verify the manufacturer designation carefully, as Unitrode was acquired by Texas Instruments. Confirm the specific suffix 'MWP' corresponds to the TSSOP-28 tube packaging variant. Ensure the datasheet matches the required isolation voltage ratings and thermal specifications for the target application environment before procurement.

Selection Notes

Select this component when a single-channel high-speed isolator with integrated termination is required for SCSI or similar high-speed digital buses. Compare against other UCC56xx series variants if multiple channels or different package sizes are needed. Verify that the 2.7V to 5.25V supply range aligns with the system power architecture.

Part Context

This part belongs to the UCC56xx family of high-speed digital isolators. These devices are engineered to replace traditional optocouplers in high-speed applications, offering superior performance in terms of speed and reliability. The family typically includes variants with different channel counts and package options to suit various board space constraints.

Replacement Considerations

Check for direct cross-references within the UCC56xx series, such as the UCC5672PW (SOIC-28) if pin-compatible packaging changes are acceptable. Verify electrical parameters like propagation delay and isolation voltage against alternative high-speed isolators from other manufacturers if sourcing issues arise.
